NEW YORK (MainStreet) - 'Twas the season for giving, but now 'tis the season for weight loss.

Just in time for the new year and its residual resolutions, weight-loss service Jenny Craig is offering a new program that monitors participants’ physical activity to ensure that their caloric intake will lead to weight loss.

Those who sign up for Jenny Craig's Metabolic Max program wear a lightweight armband that measures how many calories clients burn at any given time. The data are uploaded to the company's online database and used by clients and counselors to create meal plans for the weeks ahead.

However, according to USA Today, while costs vary depending on the client,  the Metabolic Max program costs $499 a year, about $100 more? than the comparable Jenny Craig program that currently exists.

According to Jenny Craig, the new program is designed to account for both of the elements crucial to weight loss: diet and exercise. Dieters get an armband, a year's worth of consultations and food for a week.

"We are the only weight loss company to offer a personalized approach to monitor calories in and measure the amount of calories out with," Patti Larchet, CEO of Jenny Craig, said in a press release.

Due to the hefty fee for a pedometer, MainStreet feels the need to point out that frugal dieters may find it more cost effective to enroll in the old program, purchase this $20 pedometer and go on a nice, long walk.

After all, the current Jenny Craig program has proven effective. A clinical trial published in the October 2010 edition of Journal of the American Medical Association, conducted for the company by an independent researcher, found that participants lost an average of 10% of their body weight after one year compared to 2% of those who dieted on their own.
